OK, this is all a bit beyond Indy, who I seriously doubt entered any numbers at all into the game because he failed to understand what was being asked of him. But had he been able to grasp the concepts involved, the odds are good that he would have entered some sequence of numbers like "1,2,4" or perhaps "4,8,16" to test the hypothesis "The rule is to double the numeric value of each succeding number in the sequence.

As it happens, all such sequences obey the rule.

Part 2

Only trouble is the correct rule is NOT "Double the numeric value of each succeeding number in the sequence." This was a false belief that results from confirmation bias.

You might consider testing your beliefs, the important ones anyway, by occasionally trying to disconfirm them rather than seeking only to confirm them. To do so improves your odds of believing things that are true.

Dick - you have no idea how I go about confirming or not confirming things and that test tells you nothing about me in that regard. What's happening is YOUR confirmation bias is leading YOU to believe something about me based on insufficient evidence.
